۹ نتیجهA Novel System-Level Calibration Method for Gimballed Platform IMU Using Optimal Estimation
An accurate calibration of inertial measurement unit errors is increasingly important as the inertial navigation system requirements become more stringent. Developing calibration methods that use as less as possible of IMU signals has 6-DOF gimballed IMU in space-stabilized mode
A nonlinear navigation observer using IMU and generic position information
This paper deals with the problem of full state estimation for vehicles navigating in a three dimensional space. We assume that vehicle is equipped an Inertial Measurement Unit (IMU) providing body-frame measurements angular velocity, specific force, and Earth’s magnetic field. M
Hybrid marker-less camera pose tracking with integrated sensor fusion
This paper proposes an algorithm for visual-inertial camera pose tracking, using adaptive recursive particle filtering. The method benefits from the agility of inertial-based and robustness of vision-based tracking. A proposal distribution has been developed for the selection of
Sigma - Point Kalman Filters for Nonlinear Estimation and Sensor - Fusion - Applications to Integrated Navigation - Rudolph
Nonlinear estimation based on probabilistic inference forms a core component in most modern GNC systems. The estimator optimally fuses observations from multiple sensors with predictions from a nonlinear dynamic state-space model of the system under control. The current industry
Kinematic Model-Based Pedestrian Dead Reckoning for Heading Correction and Lower Body Motion Tracking
In this paper, we present a method for finding the enhanced heading and position of pedestrians by fusing the Zero velocity UPdaTe (ZUPT)-based pedestrian dead reckoning (PDR) and the kinematic constraints of the lower human body. ZUPT is a well known algorithm for PDR, and provi
EVOLUTION OF SHUI - rLE AVIONICS REDUNDANCY MANAGEMENT / FAULT TOLERANCE Jack
The challenge of providing redundancy management (RM) and fault tolerance to meet the Shuttle Program requirements of fail operational/fail safe for the avionics systems was complicated by the critical program constraints of weight, cost, and schedule, This paper addresses the ba
Development of a Full-sized Bipedal Humanoid Robot Utilizing Spring Assisted Parallel Four-bar Linkages with Synchronized Actuation
Besides the difficulties in control and gait generation, designing a full-sized (taller than 1.3m) bipedal humanoid robot that can walk with two legs is a very challenging task, mainly due to the large torque requirements at the joints combined with the need for the actuators' si
High-Sensitivity GNSS Limitations in RF Perturbed Environments
Low signal power make stable GNSS signal acquisition and tracking difficult under RF perturbed conditions such as in signal shaded environments and in the indoors. These difficulties result in higher measurement noise, multipath (signal reflection) and, in some cases, signal deni
Deep Learning for Automatic Stereotypical Motor Movement Detection using Wearable Sensors in Autism Spectrum Disorders
Autism Spectrum Disorders are associated with atypical movements, of which stereotypical motor movements (SMMs) interfere with learning and social interaction. The automatic SMM detection using inertial measurement units (IMU) remains complex due to the strong intra and inter-sub
